I am on board with those above, would buy more than one or two plant's. The more plant mass, the more beneficial for the ammonia reducing capabilities ,and also will support less algae.
Java moss would provide shrimplet's places to hide from platy's ,who I fear would happily consume any small shrimp's they happened upon.
Water sprite is good, fairly fast grower under low to high lighting, and lot's of this along with the Moss,java fern, and anubia would be good addition's in my opinion.
Some small pieces of wood, and some smooth stones piled around the wood would also help give shrimp more protection.
Course, if your up to your ear's in shrimp's,,perhap's some predation would not be troublesome.

Ok heres what im thinking haha, anchor some java moss to tumbled rocks, and just have a pennywort planted in my gravel substrate. I also have some decor to provide hiding places. I only have a 10 gallon tank. And doesn't the shrimp take care of some of the algae? Im just asking. U guys know more than i do hahaha. And btw i really appreciate all the help

Yes,this will work.
Pennywort will grow toward's surface and after a bit,you'll have enough to also float some.
Platy's are prolific breeder's and ten gallon tank will be quite small for the number's of fry the platy's are capable of producing in fairly short order if males and females are present.
If you do not try and use too much light,and you have decent,healthy plant mass, then algae will have more difficult time forming. Shrimps will eat a little algae, but algae in excess will cause plant's to suffer.
best to try and keep algae to minimum from the outset.
When anchoring the java moss, try spread it out a liitle, so that light can reach larger surface area than it can if moss is attached in clumps, where light/nutrient's can't penetrate to center of said clump.

So i guess the crayfish would be a bad idea. What if i got 2 female platy, and because they can store sperm they might pop a couple times. But i could find a hhome for any male platy that are made. So there will be some births but not and extreme amount. Would that work?

I would be looking at small tetra's such as glowlight ,silver tip,pristella,blood fin.
These are small, hardy,active fish that do well in wide range of water and they in my view would be best suited for small ten gal.
With lot's of plant's , shrimp might not have as much to fear,and perhap's a dozen tetra's of one of the afore mentioned species would be the path I chose.
